  Add a "server" column to the schema, or to the query, with NULL value.

  There is no "sql_num_rows" function in postgres, which is needed by
the NAS initialization routines.  I guess it should be added.

  see: ... numfields = PQnfields(pg_sock->result)

  in the "query" routine.  Maybe this can be stored in the header, like
'affected_row', and returned...

  As always, patches are welcome.
